PowerPoint 2016 exported mp4 video "jerks" on some slide transitions

I am using PowerPoint 2016 - Windows 7. When I export to an mp4 video, I notice that at some slide transitions the video "jerks" (quickly flashes back and forth from previous slide). I am at a total loss as to why. I'm hoping this is something I am doing wrong and someone can help figure out how to prevent this from happening.

where it jerks: 55 seconds, 1:45, and 2:36

The same behavior occurs in original mp4 file exported from ppt. If you download the mp4 file and run in Windows Media Player you will see the glitches at the time points. For some reason, when I just run the mp4 in a browser, the jerks do not show up, I guess are "smoothed over" by whatever video player the browser is using.

You will notice there is kind of a pattern. Approximately 50 seconds between the glitches. I have noticed a more or less similar pattern, approximately one minute between the glitches, in some other tests I have done.

I also see this happen when I remove the slide timings and set the mp4 video export to advance slides every 5 seconds. In that case, the jerks happen exactly at 1 minute and 2 minutes.

The transition "jerk" never happens when I run a slideshow from within PPT. Only happens in exported mp4 video.

Slide transitions set to "none".

Any help appreciated. Please let me know if additional information needed.

If a bug in ppt, any suggested workaround?

I too have this issue. The exported MP4 from O365 PP 2016 is experiencing the same "glitch" on transitions. After the transition completes, the previous slide pops up, sometimes the entire slide, sometimes only parts of it.

I've been using PP for this purpose for many years and never had this issue, even with Win 10 x64 and O365 2016 until recently. I'm suspecting it has something to do with one or more of the updates pushed out by Microsoft. (remember the debacle where the Win 10 update 1809 would delete your user profiles if you didn't store them in a "traditional" location?)

Anyway, in October this was working fine for me (we are a corporate entity that updates much slower than public users).

I've had to resort to two rounds of encoding making the process more lengthy.

Length of video is irrelevant unless of course it's shorter than the 55 seconds (yes mine also initially happens at 55 seconds go figure)

I am a software engineer and I can tell you that this is most definitely an encoding problem. It is NOT a player problem ... I suspect that the encoding is screwed up and some players more readily ignore them. But what do I know, I only design and write software for a living.

    Handbrake will remove the jitter that I see at nearly every slide transition but that is not a solution for all situations.

    We have hundreds of students trying to make videos of Powerpoint presentations, it is unrealistic to expect them to use Handbrake or another video converter to solve a problem in Powerpoint's video export encoder.

    Things are not made any better by Microsoft seemingly having no interest in fixing the problem or in making it easy for users to find workrounds - e.g. the pressure put on the OP to close this thread before [Stephans] workround was posted.

    FWIW I'm using fully patched Windows 10 and Office 365. The problem has been present for about 2 years. The problem did not exist that I can recall in 2019 and earlier versions of Windows and Office

    Thank you very much for your reply. I am deeply moved by the efforts put into writing out all details contained in all of your replies.  I am sorry that the thing that worked for me didn't work out for you, and I never expected it to work for all the cases but a few.

    I am just a user, just like you, and I understand how frustrated we become by these annoying problems since we often work in deadlines, and wasting two hours (two days or weeks in some cases) on fixing a small issue gets to our nerves. 

    To be honest, the PowerPoint I was working on was made by my 10- & 11-year-old kids. And, they themselves solved it by following some screen recorder software. And, they prefer Google slides and other free Google products for all their online assignments ( I am also gradually moving all my simple needs away from MS to open source or freer solutions, as I have been continually beset by issues in Outlook and Windows credential manager also).  But, I just gave it a shot by doing what I wrote in the earlier message.

    This reply of mine is not adding any value, I just used the occasion to thank you and to vent out some of my frustration.

    Thank you.

    Thanks again for responding. Yes, I agree, the "jerks" show up when the video is played in some viewers, do not show up when played in others. It is puzzling. However, it is unclear (to me) what you mean by "the code" when you say "problem is in the code". Could you clarify? And as to "not a problem with the video itself", it seems to me that if the video "hiccups" when played, there must be a hiccup in the video file. Or are you suggesting that WMP and VLC somehow decide to jerk exactly at the slide transitions? Instead, I would suggest that the "jerks" are such a quick thing that some video players "gloss over" them in some fashion, in other words do not read all the video frames and end up ignoring the very few frames with the jerks. Any thoughts on that?

    Due restrictions, I am not able to view your sample file. I want to request a shorter video of your issue, and share your sample file through OneDrive. Here is the link for instructions. That way, we can review your file and suggest a proper solution for your concern. 

    We'll wait for your response.

    Bob
